ROTARY MOTOR.

Specification of Letters Patent.

Patented Mar. 12, 1918.

Continuation of application Serial No. 70,432, filed January 5, 1916. This application filed November 25,

T 0 all whom it may concern:

Be it known that 1, Jose Mor son, a citizen of Sweden, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Rotary Motor, of which the following is a full, clear, and exact description, this being a continuation of the application Serial No. 7 0, 132, filed by me on January 5, 1916.

The object of the invention is to provide a new and improved rotary motor which is veryvsimple in construction and more especially designed for using steam as the m0- tive agent and with the steam acting expansively.

In order to accomplish the desired result, use is made of a pressure chamber connected with a suitable source of steam supply such as a boiler, and a wheel mounted to rotate freely in the said chamber, the said wheel being provided with a passage having engaging obstacles adjacent to the peripheral face of the wheel, said passage having an entrance opening leading into the pressure chamber and the passage terminating at its end in an exhaust.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure '1 is a cross section of the rotary motor;

Fig. 2 is a sectional side elevation of the same on the line 22 of Fig. 1;

Fig. 3 is a side elevation of a modified form of the steam wheel;

Fig. 4 is a face view of another modified form of the wheel;

Fig. 5 is a side elevation of another modified form of the wheel;

Fig. 6 is an enlarged sectional side elevation of a portion of the wheel of modified form;

Fig. 7 is a sectional side elevation of another modified form of the motor; and

Fig. 8 is a similar view of another modified form of the motor.

The pressure chamber 10 of the rotary motor is provided with a base 11 for fastening the motor to a suitable foundation. Within the pressure chamber 10 is arranged a wheel 12 provided with a shaft 13 journaled in suitable bearings arranged in the Serial No. 133,330.

heads of the pressure chamber 10, and one outer end of the shaft 13 is provided with a suitable pulley or other means for transmitting the power of the rotary motor to other machinery. The pressure chamber 10 is provided with an inlet 15 connected with a steam boiler or other source of steam supply, and the said inlet 15 may be arranged on theperipheral face of the pressure chamber or at the heads thereof and near the center of the wheel, as indicated in Figs. 7 and 8.

The wheel 12 is provided with a working passage 16 extending adjacent the periph eral face of the wheel, and the entrance end 17 of this working passage 16 opens into the pressure chamber 10. The other end of the passage 16 connects with a radially disposed exhaust port 18 formed in the wheel 12 and leading to an exhaust port 19 formed in the shaft 13 so that the exhaust steam can be carried to a suitable place of discharge. Within the passage 16 and preferably at the outer and inner walls thereof are arranged alternately disposed engaging obstacles 2O and 21 against which acts alternately the steam in its travel through the passage 16 from the entrance end 17 to the exhaust port 18 to rotate the wheel 12 in the direction of the arrow a2. By reference to Fig. 1, it will be noticed that the engaging obstacles 20 and 21 are inclined in the opposite direction in which the steam travels through the passage 16, the said engaging obstacles forming buckets-for the steam to press against with a view to rotate the wheel 12 in the direction mentioned. The engaging obstacles 20 and 21 may be made in various shapes, as will be readily understood by comparison of Figs. 1 and 6, and the entrance ends 17 may be at the peripheral face of the wheel 12 or at the sides thereof, as shown in Fig. 7 or at the inner face of the rim of the wheel, as shown in Fig. 8, which latter also discloses two passages 16 arranged one alongside the other.

It will be noticed that the exterior surface of the wheel 12 is spaced from the interior surface of the pressure chamber 10 so that steam passing into the pressure chamber can enter the passage 16 at the entrance end 17 in any position the latter may be during the rotation of the wheel 12. Thus a continuous flow of the steam is bad through the passage 16, and by providing a large number of en- 11 gaging obstacles 20 and 21 the pressure of the steam is utilized to the fullest advantage. By reference to F ig. 2 it will be noticed that the passage 16 is restricted at the points of the engaging obstacles 20 and 21 so that the steam acts on each obstacle during its travel through the passage 16.

In the modified form of the wheel 12 shown in Fig. 3, use is made of a number of working passages 25, 26 and 27, each having an entrance end 28 and an exhaust end connected with an exhaust port extending through the wheel and its shaft, the same as above described in reference to the wheel shown in Figs. 1 and 2. In this case the entrance ends 28 are spaced equal distances apart so as to counterbalance the action of the steam in the several passages to insure an easy running, at the same time increasing the power of, the engine correspondingly.

Instead of having the wheel 12 provided with a single or a plurality of passages, each extending almost throughout the entire peripheral face, use may be made of a number of peripheral working passages 30,31 and 32, each having an entrance end 33 and an exhaust end connected with the exhaust port 3 1 leading to a port 35 in the shaft 36 of the wheel 12. The inner passage 16 shown in Figs. 1 and 2 may be arranged spirally (see Fig. 5) so that a number of convolutions are Copies of this patent may be obtained for provided but the passage has one entrance end and an exhaust end, the same as de- A steam motor, comprising in combination a pressure chamber to be in connection with a steam supply, a wheel within the said pressure chamber and out ofcontact with the walls of the chamber except at axle to rotate freely in steam, said wheel having a passage parallel to and located at the peripheral face of the wheel, the passage having an entrance opening from the pressure chamber, a central exhaust extending through the axle to the outside, and an exhaust connection between the terminal end of the said annular passage and the said central exhaust, and engaging obstacles filling the said passage and disposed in close proximity one relative to the other to allow the steam to pass but exhausting its energy.
